RADIATING SYSTEM FOR BODY WARMING DEVICES The present invention relates to improvements in a body-warming device and more particularly to a novel type of safety radiating system usable for a pocket heater, a foot warmer and any other portable warming devices using liqu'efied gas as fuel so as to take advantage of the character of the gas that, when contained, can be compressed liquescently to the minimum of volume but in use can be inflated gaseously to the maximum of volume, which comprises a liquefied gas container made of or covered with a heat-resisting and adiabatic material, a gas supply pipe connected thereto, a radiating system communicated to the pipe, and a safety appliance adapted to stop supply of the fuel when over-heating takes place.

Most of the conventional body-warmers in habitual use are known as a type wherein a carbonized substance such as charcoal, oval briquettes or the like are used to provide for a heat-source, a type wherein an electrothermic wire is adapted to develop heat, or a type wherein volatile liquid such as benzine is used for fuel. However none of the above-mentioned types are free of the following drawbacks. Namely, in the bodywarmer of a type utilizing as fuel the above-mentioned carbonized substance there is a fatal defect that it is much troublesome for a user to dispose of the ashes to which the substance was reduced by combustion and to clean up the interior of the body-warmer. In the bodywarmer of a type adapted to use an electrothermic wire as a radiating element, especially wherein dry cells are used to provide for electricity, the electric powerto be consumed by the body-warmer is considerably great, resulting in being economically disadvantageous, and further in case of using the body-warmer of said type wherein an outlet or plug socket is employed to obtain electricity, the place for use of the body-warmer is extremely limited subject to the length of an electric cord adapted to connect the outlet to the body-warmer, thus there being brought about the additional disadvantage that a user cannot always carry it with him since, as is often the case with this type of body-warmer, he cannot always find such a place accessibly installed with the plug.

With the view to eliminating or mitigating the abovementioned defects and disadvantages, a different type of body-warmer is widely used in which volatile liquid such as benzine is impregnated in cotton, gauze or any other similar fibrous tissues having absorbent properties padded in the fuel container of the body-warmer so that the liquid is oxidized in the presence of catalyst comprising platinum disposed adjacent to a burner provided in the opening of the fuel container. However, this different type of body-warmer utilizing benzine or other similar volatile liquid as fuel is also found to be still not free of the following deficiencies: in the first instance, according as the burner is gradually heated, the

heat of the heated burner is directly transmitted to the fuel container, allowing the volatile liquid to vigorously escape into vapor thereby activating the combustion of the liquid to such an extent that the temperature of the body-warmer is improperly raised along with the passage of time until at last the liquid is too much vaporized to keep its combustion efficiency, the result being that the vaporized liquid is incompletely burnt and escapes into the atomosphere through the burner, subsequently dispersing an offensive smell peculiar to benzine or similar volatile liquid; in the second place, the

construction of said body-warmer being such thatthe liquid fuel filled in the fuel container is fed to the burner by a capillary action through a fibrous tissue core, the supply or calorific value of the liquid fuel cannot be selectively controlled as desired since the diameter of the core is previously determined; thirdly, if the burner is face downwardly there is caused such fear that the liquid fuel in the fuel container should run out of the container by a law of nature; fourthly, when a user wants to stop the combustion of the liquid fuel, he must take the burner body off the fuel container, and even after the combustion was completely stopped, he must further keep the burner body removed until it is cooled off before he puts it again on the fuel container so as to see it that the remaining heat should not give rise to unforseen ignition of the burner thereby to secure the subsequent safe reuse of the body-warmer; and lastly, in pouring the liquid fuel into the fuel container, either a hopper or a fuel injector must be applied to the inlet of the fuel container in order to preventthe fuel from getting spilt from the margin of the inlet.

According to the body-warmer of the present invention, liquefied gas such as butane (C4H6) is used for fuel in place of benzine or like volatile liquid fuel in order to eradicate all the above-mentioned defects and disadvantages and further to provide the best usage of such distinctive quality peculiar to liquefied gas that is usable as the fuel in a state compressed to the minimum of volume and yet potentially provided with the maximum of calorific value. For example, it has been empirically proved that a calorific value to be produced by benzine fuel of 100 volume density comprising normal hexane can be obtained by butane fuel of volume density under 5 atm. comprising normal butane. Thus, in addition to the convenience that such liquefied butane fuel is easily available on the market in the form of compressed gas fuel contained in a fuel tank for cigarette gas lighters, the present invention provides for an advantage that the construction of the safety radiating system and the fuel supply system can be much simplitied, the result being that a variety of body-warmers such as a pocket heater, a foot-warmer and the like can be produced by applying thereto the technical idea of the present invention.

According to the safety radiating system of the invention, it is also induced to understand that the system can be applicably embedded for example in a suitable portion or portions of winter clothes, the seat and/or back of an armchair, a sofa cushion, a mat and the like. Further when the system is provided in arctics, it can always keep the inside of the arctics in comfortable warmness since a radiating means connected to the system works to automatically stop the radiating operation of the system when the arctics are heated over a fixed degree of temperature.

Accordingly, the present invention has for one of its main objects the provision of a novel safety radiating system thereby eliminating all the defects of the conventional body-warmers.

Another object of the invention is to provide such a novel and widely applicable safety radiating system for available liquefied gas for a heat-source.

Another object of the invention is to provide a novel safety radiating system for a body-warmer that can be incorporated with arctic shoes and boots, winter clothes, the seat and/or back of an armchair, a sofa cushion and the like.

A further object of the invention is to provide a novel safety radiating system for a body-warmer that is safe in use, producible at a low cost and handy in operation.

A still further object of the invention is to provide a novel safety radiating system for a body-warmer that is comprised of a liquefied gas container either made of or covered with a heat-resisting material, and a radiating portion which is provided independently of said container to burn said liquefied gas in the presence of catalyst comprising such a metallic element as platinum, palladium or the like, said container and said radiating portion being connected to a fuel feed duct that is made of heat-resisting material and connected to a safety radiating stop means adapted to stop the supply of the fuel when said duct is heated over a fixed degree of temperature.

These and other objects and advantages of the present invention will become apparent from the following description made with reference to a prefered embodiment of the invention shown by way of example in the accompanying drawings and from the appended claims.

In the drawings;

FIG. 3 is, similar to FIG. 2, a perspective view schematically illustrating the same system, and especially showing how the safety means actuates to stop supply of the fuel,

FIG. 4 shows a practical application of the system to a foot warmer or a pocket heater, and

FIG. 5 shows a practical application of the system especially to the sole portion of a shoe in which the system is embedded.

Referring now to the drawings, a safety radiating system for a body-warmer in accordance with the present invention essentially comprises a fuel storage tank 10, a radiating means 20, a fuel feeder 30 for feeding fuel from said tank to the radiating portion of said radiating means 20, and a safety means 50 for thermostatically acting on super-heating.

Said fuel storage tank 10 is preferably formed with a metallic tank 11 sheltered for example with a heatproof, adiabatic cover 12 composed of fluorine resin, silicone resin or the like, and has an inlet 13 provided in a suitable position of the tank 10 so as to allow the fuel to be poured therein through the inlet 13. However, said fuel storage tank 10 may be formed with no more than said cover 12 which is thick enough to support the internal pressure of compressively liquefied gas fuel hermetically sealed in the tank 10, and in this case said metallic tank 11 may be omitted.

On the other hand, in the event that the system of the present invention is applied to a small size pocket heater designed to produce a substantially high warming effect of long duration at small calorific value, it has been empirically found that said metallic tank 11 may not necessarily be sheltered throughout its outer surface with said cover 12, but said tank 11 may be partially sheltered with said cover 12 thereby adiabatically protecting the portions of the fuel storage tank 10 to which heat is collectively conducted.

Incidentally, said fuel feed inlet 13 is substantially same in construction that a fuel feed inlet of general cigarette gas lighters available on the market is whereby liquefied butane gas contained in any compressive gas tank for said lighters can be advantageously used as the fuel for the system of the invention.

As is shown in FIG. 2, the radiating means 20 has one end ofa metallic pipe 33 having an integral burner portion 34 which is provided in its adjacency with a pinch of asbestos, glass wool or the like which serves as a carrier 22 for catalyst 21 composed of platinum, palladium or a mixture thereof.

Said carrier 22 is not altogether limited to asbestos and glass wool but it may be any other suitable heatproof fibrous materials or block shape elements available for carrying the catalyst. Incidentally, reference numeral 23 designates a protective metallic mesh netting cover adapted to prevent the scattering and losing of the carrier which includes the catalyst. Reference numeral 24 designates a metallic fixture for securing said netting cover 23 to the base of the body-warmer. The fuel feeder 30 comprises said metallic pipe 33 communicated to the radiating means 20, a metallic pipe 32 connected to a fuel supply control means 40 communicated directly with the fuel storage tank 10, and a non-metallic adiabatic pipe 31 which is made for example of fluorine or silicone resin material and adapted to joint said metallic pipes 33 and 32 together.

Thus due to this jointing function of said non-metallic adiabatic pipe 31, the heat produced in the radiating means 20 is prevented from being transmitted thermoconductively to the fuel storage tank 10 through said control means 40 thereby completely protecting the tank 10 against such jeopardy that otherwise the liquefied gas 14 filled up therein might be easily ignited.

Said control means 40 comprises a fuel supply opening and closing member 41 adapted to be cooperative with the activation of a safety means 50 which will be described hereinafter, and an adjusting means 42 for minutely regulating the flow of liquefied gas fuel.

As are shown merely by way of example in FIGS. 2 and 3, said member 41 and said means 42 may be of commercially available types produced by the prior art method developed in the field of cigarette gas lighters, the detailed constructions thereof being not the subject matter of the present invention. However, for a full understanding of the embodiments shown in FIGS. 2 and 3, said fuel supply opening and closing member 41 is provided with a substantially cylindrical chamber 43 communicated with a gas ejecting passageway 43a having a small diameter. A valve means 44 is adapted to open and close the passageway 43a and substantially larger in diameter than the latter. Said valve means 44 is mounted to a member 45 having a spatial room 45a communicating with the interior hollow portion 32a of a metallic pipe 32 mounted so as to reciprocally move in the inside of said cylindrical chamber 43.

Between the member 45 and the valve means 44 is bored at least one small orifice 45b through which when the valve means 44 is opened, said spatial room 45a and said passageway 43a are intercommunicated with one another.

Said adjusting means 42 is provided with an outer cylinder 46 having a grooved inner periphery, an inner cylinder 47 having a grooved outer periphery to screwably engage with said inner periphery, and a subsequently described compression coil spring 46b convoluted on the metallic pipe 32 in the cylindrical chamber 43.

Said inner cyliner 47 has a prism shape head 47a and a collar 48 fixedly sleeved on said head 47a. In said collar 48 is screwably inserted a screw 44a having a small operating knob so that the inner cylinder 47 is screwably moved back and forth to the outer cylinder 46 by operating the screw 48a.

Further, to one end of the inner cylinder 47 is attached an elastic element 49 which has a plurality of relatively small holes and is composed for example of neoprene whereby according as the inner cylinder 47 is screwably advanced, said elastic element 49 is compressed to become less porous.

Said safety device 50 is essentially comprised of a bimetallic actuator Sl, at least one pivotally movable arm 52 and a reciprocating contact member 53 fixedly mounted to the aforesaid metallic pipe 32 thereby to actuate said fuel supply opening and closing member 41. The bimetallic actuator 51 is formed with a pair of metallic plates 51a and 51b which are placed one above another, and of which the former plate 51a placed above is substantially greater in the coefficiency of expansion than the latter plate 51b placed thereunder so that when they are heated over a fixed degree of temperature, they are downwardly bent to form a bow shape curvature.

ln operation of the safety radiating system of the present invention, liquefied gas fuel is firstly injected into the fuel storage tank 13 through the inlet 10.

Nextly a projection 52a formed on said arm 42 is operated by the finger-tip in the direction shown by the arrow Q until the arm 52 is pivotally moved to the foremost end of the metallic plate 51a and retained on a retaining portion 51c formed thereon. Along with this movement of the arm 52, the contact member 53 is transfered to the direction of the arrow R opposed to the arrow 0. Then the metallic pipe 32 fixedly mounted to the contact member 53 and the member 45 incorporated therewith are also jerked together with the contact member 53 in the direction of the arrow R whereby the valve means 44 provided on said member 45 is moved off the passageway 43a and release the closed condition thereof, consequently the gasified fuel 14 being admitted to eject outwardly of the passageway 43a through the porous elastic element 49 from a small hole 15 of the fuel container 11.

In this case, the passageway 43a being released by the opened valve means 44, the gasified fuel 14 is further permitted to permeate in the spatial room 45a from the passageway 53a, and then through the interior hollow portion 32a of the metallic pipe 32 to the non-metallic adiabatic pipe 311 and the metallic pipe 33 until at last it is supplied to the radiating system from the burner 34.

The gasified fuel ejected from the burner 34 is then ignited for example by applying a match to the opening 23a formed in the center of the protective metallic mesh netting cover 23 of the radiating system 20.

in a bed, a heating device to be embedded in the seat and/or back of a sofa cushion or in a foot warmer or in each sole of arctic shoes. Therefore, it is quite natural that the quantity of air or oxygen to be admitted to the 5 radiating system is extremely small. However, in the present invention, platinum, palladium or a mixture thereof being applied to the system as catalyst, the gasified fuel, once ignited, can maintain perfect combustion with such an extremely small quantity of air or oxy- 10 gen. Namely, in case that platinum is used for catalyst mo e-stag 6s? Kcal.

Thus it follows that due to the presence of the catalyst 21 mixed in the carrier 22, the burning fuel can ra- 20 .diate 487 Real not by inflammable combustion but by 6 Incidentally the radiating system of the present invention is generally designed to be suitable for use with a pocket heater generally covered with a cloth bag so e...!9. 1 assist.. hasssttaWarmest P9129! catalytic combustion, iii remarkably enhancing fife warming effect.

Although the greater the flow of gasified fuel is, the greater warming effect it can develop, yet the overflow of fuel will be a cause of superheating. Thus in order to control the fuel flowing, the fuel flow adjusting means 42 is adapted to serve for the purpose by adjusting the porosity of the elastic member 49 mounted to said means 42. That is, if a knob of the screw 48a is operated to screwably forward the inner cylinder 47, said elastic member 49 is compressed to become less porous so that the flow of the gasified fuel is decreased. On the contrary, if said knob is operated to screwably move back the inner cylinder 47, said elastic member 49 is expanded to become more porous so that the flow is increased to radiat greater calorific volume.

The non-metallic pipe 31 of the fuel supply means 30 is comprised of a fluorine or silicone resin material so that the conduct of heat caused in the radiating system is intercepted by said pipe 31. Further the fuel container lltl is adiabatically covered with a fluorine or silicone resin material so that the liquefied gas 14 in the fuel storage tank 110 is protected against superheating which otherwise may be caused by radiant or convective heat of the contained fuel and the heat to be conducted to the tank from the mounting base of the radiating system. Incidentally, a fluorine resin is heat-proof up to the temperature of approximately 1,500C.

The construction of the radiating system in accordance with the present invention is such that even if the system in use radiates heat capacity more than necessary, the bimetallic actuator 51 is bent downwardly to form a bow shape curvature as is shown in FIG. 3 whereby the retaining portion 51c formed at the foremost end of the stopper 511 falls down to release the engaged relation of the actuator Ell with the arm 52, the result being that the arm $2 is pivotally moved in the direction shown by the arrow P by the expansion of the compression coil.

Then the foremost end of said arm 52 is allowed to swing in the direction of the arrow S to release the engaged relation of the arm 52 with the contact member 43 whereby the compression coil spring 46b is also released from its compressed condition to extend to repellently press the portion in the opposed direction of the arrow R so that the valve means 44 is operated to close the passageway 43a to result in stopping the flow of gasified fuel.

As has been seen in the present embodiment, the compression coil spring 46b is so adapted that when it is allowed to extend it can work direct the interconnected pipes 31 and 32 toward the arrow S. However, said compression coil spring 46b may be replaced with a suitable extension coil spring so adapted that it is normally kept in an extended state when the valve means 44 is to be released, but when compressed, it can jerk the valve means apart from the passageway 43a. Further it is also possible to provide for a supply of gas fuel by constructing the valve means in a manner that it can let out the gas fuel when moved in the direction of the arrow S contrary to the preceding embodiment.

In order to supply again the burner 34 with fuel, the member 52a of the arm 52 is operated by the finger-tip to return to its original position shown in FIG. 2. In FIG. 4 there is illustrated an embodiment wherein the radiating system of the present invention is applied to a pocket heater or a body-warmer, and according to which the system is housed in a casing 73 connected by a hinge 71 in opening and closing relation with a cover 70 having a plurality of air inhaling holes 72, and is provided with an ignition means 60 which eliminates the disadvantage that otherwise a user must take the trouble of applying a match to the burner 34 each time he wants to ignite the same. Said ignition means 60 includes an electrothermic wire 65 provided adjacent to the burner 34. Said electrothermic wire 65 forms an electric circuit with at least a dry cell 61 provided in a suitable position of the casing 73, cords 62, 63 and a switch means 64. By closing said switch means 64, said electric circuit is electrified to be heated red thereby igniting the liquefied gas fuel ejected from the burner 34.

In this connection, the above-mentioned igniting purpose can also be performed by applying a match to the opening 23a of the radiating system 20.

In FIG. 5 is shown an example in which the radiating system of the present invention is applied to boots, arctic shoes, foot warmers and the like. According to this, it is preferable that such boots and the like are provided with a sole portion comprising a heat-resisting synthetic resin base plate 74 having the fuel storage tank mounted to one side thereof, the fuel feeder 30, the safety means 50, a thermoconductive aluminium or like metal plate 75 having the surface which is directly provided with the radiating means 20 and a felt sheet 76 adhesively attached to said metal plate 75. By this provision of the sole portion, the heat generated by the radiating means 20 is conducted directly to the whole surface of the metal plate 75 to warm the felt sheet 76 laid thereon, the result being that the heat is suitably moderated in said felt sheet so as to keep a user's sole with comfortable warmness.

Incidentally, between the base plate 74 and the sole of a shoe there are provided projections 77 together with the radiating system of the invention so that each unit of the system can be prevented from being crushed down by the foot pressure loaded thereon whenever a user walks, subsequently the base plate 74 being prevented from contacting directly with the sole exposed to the cold ground to be deprived of the comfortable warmness.

The safety means 50 disclosed in the present embodiment is somewhat different from that disclosed in FIGS. 1 to 4, in that the former is, in addition to the aforesaid pivotally movable arm 52, provided with another similar arm 52 so as to obviate such fear that even if the valve means is purposedly released open, it might be unexpectedly closed since the bimetallic actuator 51 and the arm 52 are liable to be disengaged due to the impacts that are given to the whole system by the walking motion of a user. If the bimetallic actuator 51 is heated over a fixed temperature, it will be bent to form a bow shape curvature and the foremost end of the bent actuator 51 presses down the free end of the arm 52' so that the arm 52 is released from its engaged relation with a retaining projection 52a. Therefore said arm 52 whose one end is pivotally supported at 52b is set free to stop its function to control the movement of the contact member 53 whereby the valve means is closed in the same way as has already been mentioned herein above, resulting in stopping a supply of gas fuel.

The detailed constructions of the safety radiating means 50 are of course variably modifiable subject to the construction of the control means 40 and the use of the safety radiating system of the present invention. Thus, it will be understood that the invention is not to be limited to the exact construction shown and described, but that various changes and modifications may be made without departing from the spirit and scope of the invention, as defined in the appended claims.
